command and extra exports

recent versions of llvm wasm-ld inserts ctor/dtor for every exports for a command. [1]
it broke a few use cases including wamr's malloc/free exports. [2]

while preview2 slide [3] p7 says "No other exports", my understanding is that component-model will use some exports like canonical_abi_realloc/free, which are essentially the same as what the above mentioned wamr malloc/free exports do.

anyway, whatever we will do for preview2, it's better to unbreak the existing use cases.
IMO, the wasm-ld patch in question should be reverted, or at least conditionalized to allow plain exports.
how do you think?

Start with the linked LLVM review D81689 and its discussion of ctor/dtor insertion, then compare the WAMR malloc/free use case with the WASI Preview2 presentation linked in the issue. Determine whether the existing export behavior should be restored or made conditional, and document the agreed direction for unbreaking plain exports.
